Metallic film photo-cathodes are rugged, have a fast response and good emission uniformity. Mg has also a relevant Quantum Efficiency in the near UV. A cathode suitable for a 1.5 cells S-band RF gun has been produced by depositing an Mg film on Cu by Pulsed Laser Deposition technique. After different optimizations, stable good results have been reached in the low field measurement scenario. A sample was deposited on a gun flange and tested in the 1.6 cell injector at UCLA Pegasus facility to prove cathode resistence in a high field environment. The results are described.

The PEGASUS laboratory at the UCLA Physics Department is a photoinjector laboratory. With a new ultrafast photoinjector laser driver, the laboratory capabilities are greatly expanded. We discuss the near term scientific goals and technical solutions proposed. The marriage of ultra short laser pulse techniques and a high brightness electron source allows also the development of advanced longitudinal beam diagnostics with time-resolution comparable to the ultrashort laser probe pulse derived from the photocathode driver.
